Security checks for vulnerabilities and agentic risk

Overview

This is a simple habit-tracking skill with disclosed local storage and no evidence of hidden, remote, privileged, or destructive behavior.

Install only if you are comfortable with habit names and check-in history being stored locally at the disclosed path. Avoid entering sensitive personal details as habit text, and note that the referenced Python script is not included in the inspected artifact.

Vulnerability Patterns

Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Findings (2)

Natural-Language Policy Violations

Low

Confidence: 80% confidence
Finding: The manifest description and primary markdown content are presented in Chinese, which can impose a language constraint on users without opt-in. The file does include an English title translation, but it does not clearly offer language selection or state that the skill is intended specifically for Chinese-speaking users.

Missing User Warnings

Low

Confidence: 87% confidence
Finding: This markdown file states that habit data is stored in `~/.memory/habits/habits.json`, which affects user data persistence. The description does not include any warning or disclosure about retention, privacy, or that check-in history will be written to local storage.
